a |vHv^0The function of these commands is very similar. The goal is to determine what processes have certain files open. lsof is freeware and thus freely compilable under all Unixes. It is available by default under Linux only.ITPUB个人空间3n-@)GO9At*|

To list all open files for login name ``abe'', or user ID 1234 you would use the -u option. To list files being used by process 456, process 123, or process 789, you would use the -p flag. Putting these criteria together, we would have a command that looks like this:

fuser is more widely available (under AIX, HP-UX, IRIX, Linux, Solaris, Tru64 UNIX, and others) and can only be run as root. It displays the process ID numbers of processes using the specified files or file systems. In the default display mode, each file name is followed by a letter denoting the type of access (these codes differ from vendor to vendor):ITPUB个人空间
